I do take exception to your statement about long-term commitments. Yes, divorce is a growing problem but there are still many, many long-time successful marriages. TCS and I are one such couple, and our daughter and her husband have just had their 20th anniversary. I have many friends who have been married 30, 40, 50+ years.
I agree that Nicole is way too flighty for anything serious at this point. (Also, serious relationships have to be a two-way street; one person's obsession for another is not a "relationship.")
